R31Nismoid Posted May 19, 2006 Share Posted May 19, 2006 definately dont need N1 crank to fit a N1 oil pump. And as stated a few times, get the 32 one tested. If its fine, then have a collar fitted and its no better or worse than a new RB26 crank cheers Link to comment https://www.sau.com.au/forums/topic/117984-time-to-rebuild-the-rb26/page/2/#findComment-2183514 Share on other sites More sharing options...
saliya Posted May 19, 2006 Share Posted May 19, 2006 well i would think the HKS kit is very good. some of the difference between the steps is as follows.step 2 has coated pistons step 3 has rods with 22mm pins and the coated pistons they all have H beam rods, step 1 and 2 are stock pin size step 3 are 22mm pin. they all have fully forged counter balanced cranks with a stroke designed to give 2.8l capacity (not sure if there is a difference between the cranks). Step 2 and 3 have a coating on the piston crowns and skirts and step 3 have titanium coated top rings. I have to say the HKS pistons are among the nicest i've ever seen. they are a piece of work. i think comparing the step 1 kit to the crower kit is more than fair. HKS have invested more money in HKS parts that crower could ever dream of. yes they have great rep in stroker kits, but no where near the RB26 experience of HKS who have been developing parts specifically for RB26 since ~1990. I'm guessing you mean 'more money in RB26 parts'; Crower is "fairly" big in the US scene, and the US scene is a "fairly" big market And no argument there; I don't think they even do stuff specially for the RB26. anyway mate i wasnt trying to pick an argument with you. i was just pointing out what you can get a japanese stroker kit for since you asked. Not at all, that's exactly the info that I was looking for; I think perhaps R31Nismoid has mis-interpreted what I was saying (to try to restate - "worst" means "worst that HKS offers" not "worst on offer"; and I've inferred "worst" from "cheapest"; don't know how to make it clearer). The Crower kit costs roughly the same as a duty-exempt HKS step-1 kit (don't think that can happen, but you never know ) Yes, the step-3 stuff looks awesome, and yes, it has a pricetag that's several thousand dollars more. But if the step-1 stuff is the goods, a buyer should look very closely at it since it's a few gorillas cheaper than step-2 or 3, OR anything similar from Tomei or Jun. Got any photos of step-1 stuff?

DAN00H Posted May 19, 2006 Share Posted May 19, 2006 just to add another angle - anyone noticed that 'cosworth' are now doing the internal parts for the RB26 - currently looking for a Aust distributor. I say'cosworth', as it is not cosworth as we traditionally know it - they are now owned by Mahle.... reason - because Mahle saw that cosworth had the reputation and expertise to both bring Mahle into the more mainstream arena and provide some excellent technical knowledge. This came from reading an interview of the CEO (or equiv, Dr someone...) of Mahle. I know what I would be getting if I was rebuilding my RB26!!

Beer Baron Posted May 20, 2006 Share Posted May 20, 2006 haha, yeah a hand model just like george costanza trying to avoid manual labour all my life! saliya, i havent bought any step 1 gear, but i did take some pics of it last time i was in japan, i will try and did the pics out. as far as i know the main differences between 1 and 3 is the coatings, the rings and the pin size. i still think the step 1 stuff would be comparable with most other brands of forgies.

Turbz_13 Posted May 21, 2006 Author Share Posted May 21, 2006 but say my crank is f**ked, what crank could i then use to suit the n1 oil pump? say a standard r33 gtr crank? would this need a collar as well? so the standard conrods will be fine to make say 400 4wkws (530 horsies)? just using new conrod bolts. any good suggestion for pistons and rings for this kinda power rating? change the standard head bolts to new ones? or will the old 1's be ok? what thinkness metal head gaskit would suit what i am going for? as im going to buy a metal gaskit kit. cheers!

Yes, a standard 33 gtr crank is fine with the N1 oil pump. No collar modification is needed for the 33 gtr crank. The standard rods will be fine at this power level. Any reputable piston brand will do - Weisco, ACL etc Link to comment https://www.sau.com.au/forums/topic/117984-time-to-rebuild-the-rb26/page/2/#findComment-2185955 Share on other sites More sharing options...

Duncan Posted May 21, 2006 Share Posted May 21, 2006 there is no such thing as an n1 crank, the n1 pump will fit over any rb26 or rb25 crank (although there are some bolt to block differences on earlt rb26s). most 32 cranks (except 94 onwards) have a smaller oil pump drive, this is not ideal although you can fit a collar to address this potential problem. but using a 32 crank without a collar is not some automatic engine death sentance Link to comment https://www.sau.com.au/forums/topic/117984-time-to-rebuild-the-rb26/page/2/#findComment-2187210 Share on other sites More sharing options...

It's a must do job to remove those screws and loctite them in when the opportunity presents.
